The Austin American-Statesman reported that Boyd was charged with misdemeanor assault following an altercation after a car crash on July 4. Boyd is accused of assaulting a 20-year-old at the scene of the crash.
In a statement, Texas coach Tom Herman said the school would "continue to monitor the legal process and pending its completion, determine any further action."
Boyd, a reserve, played in four games last season.
His brother, Kris, a senior defensive back with the Longhorns, was also in the crash on that day and tweeted about the car crash that evening.
